module: junos_system
version_added: "2.4"
author: "Ganesh Nalawade (@ganeshrn)"
short_description: Manage the system attributes on Juniper JUNOS devices
description:
- This module provides declarative management of node system attributes
on Juniper JUNOS devices. It provides an option to configure host system
parameters or remove those parameters from the device active
configuration.
options:
hostname:
description:
- Configure the device hostname parameter. This option takes an ASCII string value.
domain_name:
description:
- Configure the IP domain name
on the remote device to the provided value. Value
should be in the dotted name form and will be
appended to the C(hostname) to create a fully-qualified
domain name.
domain_search:
description:
- Provides the list of domain suffixes to
append to the hostname for the purpose of doing name resolution.
This argument accepts a list of names and will be reconciled
with the current active configuration on the running node.
name_servers:
description:
- List of DNS name servers by IP address to use to perform name resolution
lookups. This argument accepts either a list of DNS servers See
examples.
state:
description:
- State of the configuration
values in the device's current active configuration. When set
to I(present), the values should be configured in the device active
configuration and when set to I(absent) the values should not be
in the device active configuration
default: present
choices: ['present', 'absent']
active:
description:
- Specifies whether or not the configuration is active or deactivated
default: True
choices: [True, False]
requirements:
- ncclient (>=v0.5.2)
notes:
- This module requires the netconf system service be enabled on
the remote device being managed.
- Tested against vSRX JUNOS version 15.1X49-D15.4, vqfx-10000 JUNOS Version 15.1X53-D60.4.
